struct ContentView: View {
  var body: some View {
    List( Color.AdditionalColors.allCases, id:\.self) { color in
      ZStack {
        Color(hex: color.rawValue)
        Text("\(Color.mapValueToName[color.rawValue] ?? "invalid Color")")

Main functionalities

use color with name

You can specify the color with its name (in W3C/ApplePalletColor) like

let favoriteColor = Color.gold                // :)
let nextFavColor = Color.ApplePalletBrown

Note: to avoid name conflict with SwiftUI, name of all W3C colors starts with lowercase character.

for color in apple pallet, it starts with "ApplePallet" prefix.

able to convert between "color name" and "its RGB value"

2 dictionaries are there.

ApplePalletColorMapValueToName, ApplePalletColorMapNameToValue

convert between "ColorPallet/Apple" to "RGB values" like

let rgbValue: UInt32 = ApplePalletColorMapNameToValue["Brown"]
let anotherRgbValue = ...
let colorName = ApplePalletColorMapNameToValue[anotherRgbValue] ?? "undefined in pallet"

Note: what is "ColorPallet/Apple"? -> please refer to followings.

note: Colors in "ColorPallet Apple" is different from SwiftUI Colors.

W3CColorMapValueToName, W3CColorMapNameToValue

convert between "W3C named color" to "RGB values" like

let rgbValue: UInt32 = W3CColorMapNameToValue["brown"]
let anotherRgbValue = ...
let colorName = W3CColorMapValueToName[anotherRgbValue] ?? "undefined in W3C"

where comes from?

color name and RGB values comes from https://www.w3.org/TR/css-color-4/#named-colors

any restriction?

to prevent duplicate key, following colors are disabled.

• Grey (and other Greys)
  • use Gray
• Aqua
  • use Cyan
• Fuchsia
  • use Magenta

Note: SwiftUI definition is different from this extension

You can use Color.red (comes from SwiftUI) and Color.Red (comes from this extension) even both means same color.
